Sample:
Households in the Greater Columbus area with at least one Jewish adult.

Persons were considered Jewish if they considered themselves to be Jewish, were raised Jewish, or had a parent who was Jewish.

Sample Size:
739

Sample Notes:
Brief methodological discussion in the "Report."

370 interviews completed in a List sampling frame, 369 in the RDD frame (variable is "source"). List numbers which were interviewed during the RDD process were de-duplicated from list sampling frame prior to interviewing.

Weights in the data file ("regnwt1", etc.) are not extrapolated to the total number of Jewish households or persons in the study area.

List and RDD samples are apparently not weighted so the interviews cannot be combined in data analysis.

Thus, throughout the reports, the results of the Columbus 2001 Jewish population study are presented as comparisons of the RDD (random-digit dialed sample) and the Federation List sample.

For example, the intermarriage rate for the List sample is estimated to be 17%, but 45% for the RDD sample.

The authors note that, "Because the list sample represents a special population of individuals generally identified as connected in some form to a Jewish organization, extrapolation of the findings to the larger population within the geographic area of interest should be limited to the RDD sample."

Data analysis throughout the report not only compares results from the RDD and the List samples, but also compares data by whether the Jewish survey respondent was deemed to be Jewish by all definitions of being Jewish (self-identity, raised Jewish, parent Jewish) or only through some of those factors.
